GFX9 stopped using m0 for most DS instructions. Select
a different instruction without the use. I think this will
be less error prone than trying to manually maintain m0
uses as needed.

Passthrough LLVM_ENABLE_{PROJECTS,RUNTIMES} to followup stages to
support the side-by-side checkouts (aka monorepo layout).

Escaping ; in list arguments passed to ExternalProject_Add doesn't seem
to be working in newer versions of CMake (see
https://public.kitware.com/Bug/view.php?id=16137 for more details). Use
a custom LIST_SEPARATOR instead which is the officially supported way.

Previously we had an isel pattern to add the truncate. Instead use Promote to add the truncate to the DAG before isel.
The Promote legalization code had to be updated to prevent an infinite loop if promotion took multiple steps because it wasn't remembering the previously tried value.

rL319241 was a bit too aggressive removing sources dependencies. This
restores the actual required dependency for armhf.

Summary:
We want to automatically copy the appropriate mailing list
for review requests to the openmp repository.
For context, see the proposal and discussion here:
http://lists.llvm.org/pipermail/cfe-dev/2017-November/056032.html
Similar to D40179, I set up a new Diffusion repository with callsign
"OMP" for OpenMP:
https://reviews.llvm.org/source/openmp/
This explicitly updates openmp's .arcconfig to point to the new
OMP repository in Diffusion, which will let us use Herald rule H272
to automatically subscribe openmp-commits to review requests.

Summary:
From the bug report:
> The problem is that it fails when trying to compare -65536 (or 4294901760) to 0xFFFF,0000. This is because the
> constant in the instruction is sign extended to 64 bits (0xFFFF,FFFF,FFFF,0000) and then compared to the non
> extended 64 bit version expected by TableGen.
>
> In contrast, the DAGISelEmitter generates special code for AND immediates (OPC_CheckAndImm), which does not
> sign extend.
This patch doesn't introduce the special case for AND (and OR) immediates since the majority of it is related to handling known bits that have no effect on the result and GlobalISel doesn't detect known-bits at this time. Instead this patch just ensures that the immediate is extended consistently on both sides of the check.
Thanks to Diana Picus for the detailed bug report.

This isolates the per-architecture files from the common files
implementing the XRay facilities. Because of the refactoring done in
D39114, we were including the definition of the sources in the archive
twice, causing link-time failures.

Summary:
Load process memory map after updating the same cache to reflect the
umap happening in the process of updating.
Also clear out the buffer in case of failed read of /proc/self/maps (not
the source of stale segments, but can lead to the similar crash).

GIM_CheckNonAtomic has been replaced by GIM_CheckAtomicOrdering to allow it to support a wider
range of orderings. This has then been used to import patterns using nodes such
as atomic_cmp_swap, atomic_swap, and atomic_load_*.

An alloca may be larger than a variable that is described to be stored
there. Don't create a dbg.value for fragments that are outside of the
variable.
